These 7 foods release toxins if you reheat them. I never expected number 4!

There's oftentimes a little bit of dinner leftover from the night before. Maybe someone didn't show up to your party or you overestimated your own appetite while cooking. Most of us were taught to never waste food and sometimes the meal was just so tasty that you want to save some for tomorrow. But it's important to realize that not all foods are safe to store and reheat on the stove or in the microwave. In fact, sometimes reheating meals can even be poisonous! Make sure you take care with the following 7 foods:

If cooked potatoes are stored at room temperature, they can quickly grow a bacteria that can cause food poisoning. It's best to always store cooked potatoes in the refrigerator. When you are ready to eat a second round, they can be reheated in the microwave or on the stove.

The protein structure of mushrooms and their relatives is altered when they are heated up and can change in such a way that they become dangerous. Storing mushrooms at room temperature is also not recommended because they can release certain toxins if not stored properly. It's best to consume mushrooms right away and store them for no longer than 1 day in the refrigerator.

That's right, reheating rice can even make you sick. If it's stored at room temperature, food-poisoning bacteria can form. To avoid hours of diarrhea and vomiting, you should always put old rice in the refrigerator in an air-tight container. Reheating it afterwards should then be safe.

Similar to eggs, chicken is also high in protein. Reheating and consuming it can lead to stomach aches, vomiting, or diarrhea. If you really want to reheat last night's chicken, you better make sure it's completely cooked through and the middle is hot. It may be safer to just eat it cold on a salad or in a sandwich.

It's better to store dishes with these 7 ingredients in the refrigerator or maybe just decide against eating leftovers. It's always easiest to just make sure you cook the right amount in the first place!
